How Crowded Is Death Valley National Park in September?

September runs about 1× Death Valley National Park's average month, which makes it an average month here — roughly 8% of the park's yearly visitors come in September.

In a typical September the park sees about 103,000 recreation visits, based on National Park Service monthly counts from 1979 to 2025.

That makes September the 9th-busiest of the park's twelve months, sitting between the March peak (1.4×) and the June low (0.7×).

On our Best Time to Visit score September rates 53/100 ("Fair"), versus the top-rated January at 66/100 — pleasant weather with noticeably thinner crowds (shoulder season).

Typical September weather, from 1991–2020 NOAA climate normals at the nearest station, averages a daytime high near 105°F and an overnight low around 79°F.

That average of about 92°F is warm enough that midday heat is worth planning around.

Because June, July and August together draw about 22% of annual visitors, choosing September instead steps outside that summer crush — the single biggest lever on how crowded the park feels.

You'll have about 12.2 hours of daylight in September to explore — between the 9.5-hour midwinter low and the 14.5-hour summer high.

Park-wide, 2025 drew 1,320,134 recreation visits, down 8.4% from 1,440,484 in 2024.

Across the past decade overall visitation has eased about 18.3%, so September may feel a touch quieter than it once did.
